To all 'whom fit 'may concern:

Be it known that I, BERNHARD LSGHMIDT, a citizen of the United States, and a resident of Davenport,'in` the county of Scott and this mechanism, which, after it is once in v `vati'on of my improved mechanism applied motion, regulates the extent of the movement of theparts of' said mechanism and assists the operation thereof. This I accomplish by the means hereinafter fully described, and as particularly pointed' out in the claims.

In the drawings :nflligure l is a side eleto a washing machine. Fig. 2 is aview looking at the side of the machine, from a viewpoint at right angles to that shown in Fig. 1. Fig. 3 is a view similar to Fig. 2 showing a slightly modified construction of' n1y invention.

top 0f the tub. At the center of this llid,A

thereis an agitator shaft a whose upper end is j ournaled in suitable bearing in the screwplate of a supportingframe b, and whose lower end extends into the tub and is provided with an agitator 'c of a well known design. The upper end of shaft a extends through its bearings and is provided with a .bevel-gear B, which engages a correspond ing gear C secured to the adjacent end of a horizontal shaft D, which .latter extends transversely to av point `beyond theedge of the cover of the tub, and-has bearings in standards arisingfrom the screw-plate of snpportingframe t, substantially as shown. At itsl outer end `Shaft D is provided with a Fig. 4 is a view similar to Fig. 1v lshowing yet another modification of the i, pinion c, which, when the lid of the tub is closed, engages a segmental rack d carried by a leverv F, that is fulcrumed on a suitable pivotal stud f p3rojecting from a vertically disposed plate secured to the side of the tub by screws or otherwise, substantially as shown. The boss of rack d is provided with an upwardly projecting socket e into" which the lower end of said lever lF is inserted and secured. This lever continues upwards in,

a plane midway between the ends of rack d l and passes through a suitable eye e made integral with the segment from' which lthe `teeth of the rack` project. By working this lever back and forth `an alternating rotary motion is imparted to shaft D, and, through the latter, to the agitator shaft.' Thisy arrangement of the rack and pinion c permits the lid of the machine to be raised'or lowered chine and at the point of reversal of the movement of the reci rocal elements includf ing the agitator sha t, Il have provided `the segmental rack with an arm g that projectsI at right angles to the length of lever F, preferably, in a plane intersecting the axis of the pivotal stud f, the outer end of which has the upper end of a pitman G ivotally connected thereto. The, lower en pitman is pivotally connected to the crankpin of a comparatively large gear H which of this latter is journaled on a stud'h projecting :from about the height of supporting-plate VE. The diameter of the perimeter described,u

by said crank-pin is such that, when the lever F is moved back vand forth to the limit of its movement, said pitman will impart a continuous rotation to gear H. Gear H meshes with a pinion I which is made integral with the inner end of the boss of a flywheel J', that is journaled upon a pivotal stud j projectingv from the lower endl of a su portingsplate E; The fly-wheel J revolves in a vertical plane 4alongside the lower portion'of the tub, and is speeded up so as to revolve two or three times as fast as the gear H, and when this fly-wheel is once started, its momentum assists in carrying the have their lower ends 5 flattened and 'se-4 cured to the inner surface near the feet of the adjacent legs of the tub. Pinion 6 and fly-wheel 7 are journaled in bearing 3, and

Vthe gear 8, engaging said pinion is journaled.

on a stud projecting from plate 2 at a point nearer the bottom of the tub, than as shown in Figs. 1 and 2 of the drawings. The pitman 9 is necessarily made longer in ,this modification than as shown in said ltigs. l`

and 2, but the reinaindel` of the :ntnating mechanism is the same.

A In Figs. '-1 and 5 .l show yet another modiiication i-n which plate 2 remains the same as shown in Fig. 3, but, instead of having the pinion and flydvlieelvjournaled in its ,bearing 3 one end of horizontal shaft l0 is jonrnaled therein, which has its end extendedthrough said bearing and provided with a` cran'lt ll. This crank is shorter than arm g, and is connected thereto man 12. lf desired, a coiniecting-rod 13 can be pivotcd to the crank-pins of crank l1 and connect the same to one end of a treadle l-i whose opposite end may be fulcrumed in a suitable manner to a stud 15 projecting from the lower end of the adjacent leg of the tub. Shaft 10 extends horizontally under the tub to and beyond the opposite side thereof, and has the end opposite the crank journaled in` and extending through a bearing 16, in the lower end of a hanger 17. A gear.18 is securely mounted on the said extended end, which engages a pinion-19 on the inner-'end of the boss of a fiy-wheel 20which latter, together with said pinion is journaled on a stud projecting from the screw-plate 2l of the hanger, which, as shown is secured to theside of the tub.

The advantages of the modification shown in Figs. 4- and 5 of the drawings, is that the Weight of the momentum and actuating devices is equally supported by the legs and. not borne all on one side of addition to this, both hand and foot may be utilized to operate the same.

'What I claim as new is 1. The combination with cal vertical shaft, a rotary reciprocal horizontal shaft at right angles thereto, means for operatively connecting' said shafts, of a lever fulcruined at its lower end independent of said horizontal shaft, a balance wheel engaged by said the machine, and, inl

a rotary reciprof:

ing a pitman for imparting motion from said y arin to said wheel.

8. The combination with a rotary reciprocal vertical shaft, a rotary reciprocal horizontal shaft arranged at right angles thereto, means for operatively connecting said Ishafts, ot' a lever fnlcrnmed at its lower end independent of said horizontal shaft, an arm projecting :from the lo'wer end of said lever, a balance wheel whose axis is below and parallel to said horizontal shaft, a pitman whose upper end is pivotally connected to said arm, and acontinuously revoluble gear balance wheel.

4, The combination with a rotary reciprocal vertical shaft, a rotary reciprocal horizontal shaft-at right angles thereto, means mounted on the ad jacent ends of said shafts for operatively connecting the same and a pinion on the opposite end of said horizontal shaft, of a .lever fulcrumed at its lower end independent of said horizontal shaft, a balpitman that actuates saidance wheel whose axis is below said lever and parallel to said horizontal shaft, a segmental l rack carried by said lever and engaging the undermost segment of said pinion, and a gear indirectly actuated by said lever for operating said wheel.

5. The Vcombination with a rotary reciprocal vertical shaft, a rotary reciprocal horizontal shaft'at right angles thereto, means for operatively connecting said shafts, and a pinion on theouter end o f said horizontal shaft, Aof a lever fulcrumed at its loWerend whose axis is parallel tov said last mentioned shaft, a segmental rack carried thereby and engaging the undermost segment of said pinf ion, an arm projectingl from the lower end of thesame, a balance wheel and means including a pitman for impartingmotion from said arm to said wheel.

6. The combination with a` rotary reciprocal vertical shaft, ay rotary reciprocal horizontal shaft arranged at right angles thereto, means for ope 1atively connecting said shafts,

'and a 'pinion on the outer end ofsaid horizontal shaft, of a lever fulcrumed at its lower end, a segmental rack carried thereby and engaging the undermost segment of saidl im ion, an arm projecting from the lower en of the same,ea balance Wheel Whose axis is 4par- 'f my hand and seal this 29th day of February,l allel to said last mentioned Shaft, a pitman l A.
